Daniel DvorkinBrought out from a discussion elsenet: would Earth now be warm enough to support large, #nonavian #dinosaurs today? This is a fair question, because as bad as global warming is—and it's going to get worse—we're still nowhere near the hottest times of the #Mesozoic.
The answer is, it was *generally* warmer than the present day, but #global #temperatures went up and down considerably, as you'd expect over such a long stretch of time—about 175 million years from the first dinosaurs to the #Chicxulub impact. Dinosaurs as a #clade did fine the whole way through, although of course with plenty of various groups dying out in the meantime.
Also, the planet has always had warmer and cooler regions. Many large dinosaurs lived comfortably in polar regions that had #climates comparable to the cooler parts of the temperate zones today. The idea that non-avian dinosaurs exclusively inhabited steaming jungles or baking deserts has been embedded by generations of paleoart, but it's just wrong. If the impact hadn't happened, they'd still be thriving.
That being said, #sauropods in particular seemed to prefer warmer environments, so their range might be a lot more limited now than it was then, and it's possible the ice age(s) would have finished them off. Other famous giants like #tyrannosaurs, #ceratopsians, and #hadrosaurs would still be widespread, and smaller ones like #dromaeosaurs ("raptors") would be as numerous as coyotes and wildcats are in our world.

Plant-eating dinosaurs evolved backup teeth to eat tough food, research reveals
At the end of the Cretaceous, the duck-billed hadrosaurs were the most advanced herbivores on Earth. New research has revealed just how voracious these dinosaurs were, with their average tooth worn away in less than two months as they consumed enormous amounts of plants. Some of Earth's most successful herbivores may have had hundreds of thousands of teeth in their lifetime.
John Conway"Corythosaurus casuarius" — 2012
Corythosaurus casuarius was a duckbilled dinosaur, from the Late Cretaceous of North America. This a a completely reworked version of the first painting I ever did, back in 1995 or so. It owes quite a lot to a drawing of Parasaurlophus in a redwood forest by Gregory Paul.

in this podcast, Dr. Ali Nabavizadeh gives a great explanation of the differences between reptile lips, which don't have muscles, and mammmal lips, which do:

Of course it's inside a discussion on whether or not dinosaurs had lips. : ) It's about 30 minutes in.
Terrible Lizards: TLS08E07 Chewing Triceratops with Ali Nabavizadeh
Dinosaur jaws and feeding with Ali Nabavizadeh We started with theropod feeding but what about the herbivores? This week we’re joined by Ali Nabavizadeh who specialises in the jaws and teeth of the ornithischian dinosaurs and how these work and how this plays into their feeding ecology. This gives Dave ample opportunity to ask vexing questions about their jaws and elicit the same response he gives whenever asked about T. rex being a scavenger, but it does mean that Ali talks about how the hadrosaur dental battery works, how similar they are to ceratopsians and whether or not these animals have cheeks.
